I have a nepton 280l cooling system and occasionally when booting up ill hear the radiator fans spin up faster and faster. I checked the cpu temp and at idle it was at 46degrees and rising which caused the fans to spin up faster and faster. After restarting my pc it will start up normally. i have the radiator fans plugged into both of the cpu headers and the pump plugged into the system fan header. My suspicion is that the pump is intermittently failing. Any help on the diagnosis would be greatly appreciated.
